The Donald Trump administration is pushing the Indian government to lower import duties on a host of products and the failure of the dialogue to settle thorny trade disputes has prompted the US to threaten a withdrawal of concessional duty access for several Indian products under the GSP programme.

India, which is the second biggest purchaser of Iranian oil after China, had agreed to restrict its monthly purchase to 1.25 million tonne or 15 million tonne in a year (300,000 barrels per day), down from 22.6 million tonne (452,000 barrels per day) bought in 2017-18 financial year.

Early this year, at a White House event to announce his support for reciprocal tax, Trump had said he was satisfied with the Indian decision to reduce the import tariff on Harley-Davidson motorcycles from 100 per cent to 50 per cent. "Even this is not enough, this is okay," he said at that time.
